Portable Electronic Device Dual-Axis Display Rotation and Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers lack operational flexibility as their displays can only rotate along one axis, limiting their usability and ability to provide diverse operating modes.
Innovation Solution
A portable electronic device design that incorporates a sliding base with guiding portions and slots, allowing the display to rotate and slide relative to the host, enabling multiple operating modes by pivoting and sliding mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display can only rotate around one axial direction, then the structure is simple, but the operational flexibility is limited
Solution Approach 1:
The patent applies dimensionality change by enabling the display to rotate around two axial directions instead of one. The first axial direction allows unfolding and closing, while the second axial direction (perpendicular to the first) allows orientation adjustment. This dual-axis rotation system provides multiple operating modes including image sharing, external desktop display, and various viewing angles, thereby resolving the contradiction between structural simplicity and operational flexibility.
2Adaptability or versatility
If the display rotates around a second axial direction to adjust orientation, then image sharing capability is improved, but the device cannot slide on the host
Solution Approach 1:
The patent applies dynamics by introducing a sliding mechanism that allows the display to move along the host body. The sliding base includes guiding portions and sliding slots that enable the display to slide in specific directions while maintaining connection to the host. This dynamic sliding capability complements the existing rotation mechanisms, providing additional operating modes such as extended display configurations and flexible positioning, thereby resolving the limitation of non-sliding designs.
3Adaptability or versatility
If the display and base plate rotate along with the sliding rotating element, then operational flexibility is enhanced, but the positioning precision may be affected
Solution Approach 1:
The patent applies the intermediary principle by introducing positioning columns as mediators between the sliding rotating element and the guiding portions. The positioning columns engage with the guiding portions to provide precise positioning references during rotation and sliding operations. This intermediary mechanism ensures that while the display and base plate can rotate and slide to achieve multiple operating modes, the positioning precision is maintained through the constraint provided by the positioning columns and guiding portions working together.

AI summary
A portable electronic device includes a host, a sliding base, a base plate, a display and a sliding rotating element. The sliding base is disposed on the host and has at least one guiding portion and at least one sliding slot connected to the guiding portion. The base plate is disposed on the sliding base. The display is pivoted on the base plate. The sliding rotating element is fixed to the base plate and is rotatably and slidably connected to the sliding base, and the display and the base plate are configured to rotate or slide on the sliding base along with the sliding rotating element.
